The RainCode Roadmap for Informix 4GL is a RainCode product, which produces documentation out of possibly large amounts of Informix 4GL source code automatically, in order to ease maintenance, and, more generally, deliver usable knowledge about existing systems.

Modules

Each source code module is rendered in HTML form, lines are numbered, colour codes are used to emphasize various parts (SQL statements, comments, etc.) and hypertext tags are used to navigate comfortably in the source file, going from a variable use to the matching definition, etc.

Groups

The user can also define groups, and indicate which of the modules belong to each group. A module can belong to more than a single group, it is not an exclusive classification.

Typically, groups are defined by a technical criterion (batch, interactive, etc.) or by an application-level criterion (payroll, accounting, etc.)

The documentation generated by the RainCode Roadmap can be viewed by group: the user can explicitly ask to view the information of one group only, ignoring the modules of other groups. This filter-like facility comes handy when dealing with metrics applied to excessively large portfolios: for instance, if one deals with 2000 batch programs and 100 interactive programs, the ability to define ad-hoc groups allows to view metrics (including statistical distribution) measured for the 100 interactive programs, without the clobbering of the 2000 batch programs.

Cross-references

Global resources are listed together with the places where they are used, across the entire portfolio. Such global resources include:

• SQL tables,
• SQL cursors.

Metrics

The Informix 4GL Roadmap provides a set of predefined metrics. Besides these metrics, additional user-defined ones may easily be added to the RainCode Roadmap.

Metrics about the code complexity:

• Number of statements
• Number of functions
• Number of reports
• Maximum Nesting Level
• Cyclomatic complexity

Metrics about SQL:

• Number of SQL statements
• Number of different SQL tables
• Number of SQL PREPAREs

Metrics about lines:

• Number of lines
• Number of blank lines
• Number of code lines
• Number of comment lines
• Number of mixed code and comment lines
